无法将pip 9.0.1升级到9.0.3 - 要求已经满足

Question

我正在尝试更新pip使用pip install --upgrade pip,但我同时收到"需求满足"错误和"过时版本"消息

$ pip install --upgrade pip
Requirement already up-to-date: pip in 
/Users/user/Envs/proj/lib/python2.7/site-packages
You are using pip version 9.0.1, however version 9.0.3 is available.
You should consider upgrading via the 'pip install --upgrade pip' 
command.

我该如何更新？

curl https://bootstrap.pypa.io/get-pip.py | python

Answer 2

这两个命令对我有用：

curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py

然后：

python get-pip.py
